PCI Serial Boards/RS-232

PCI Bus: High performance I/O slot in every desktop Pentium, Pentium (II) and Pentium Pro PC. PCI provides improved performance to all running applications by freeing up the CPU.,PCI boards are detected and configured automatically by the PC, avoiding conflicts in address and interrupts. PCI boards automatically implement a shared interrupt system so maximising use of precious system resources.,The Windows device drivers supplied with each serial card reads the PCI assigned setup and configures your system accordingly. Products in this range are supplied with Vista and Windows drivers and are Plug-and Play compatible.,PCI 2.3 requires that all plug-in cards support 3.3V signalling. To support many older systems that use 5V signalling the following Brainboxes products are compatible with both 3.3V and 5V signalling.All the boards in this range also share the same following specifications:

Data bits: 5, 6, 7 or 8
Stop bits: 1 or 2
Parity: Odd, even, mark, none or spaces
